Odpowiedź:
a² = 4,5² + 6² = 20,25 + 36 = 56,25
a = [tex]\sqrt{56,25} = 7,5[/tex]
a = 7,5 cm
h = 18 cm
Pp = 0,5*9 cm* 12 cm = 54 cm²
V = Pp*h = 54 cm²*18 cm = 972 cm³
===============================
Pc = 2 Pp + Pb = 2*54 cm² + 4 a*h = 108 cm² + 4*7,5 cm*18 cm =
= 108 cm² + 540 cm² = 648 cm²
Szczegółowe wyjaśnienie:
" Life is not a problem to be solved but a reality to be experienced! "
